I have followed the given instructions to re-program a keyless entry remote (to the letter) but it was not successful. I just put a new battery in the remote. It is the correct remote (it worked before). Any suggestions? ---

Make certain the battery is installed right side up. And memorize the sequence of things you have to do to program it, because I have found that if I try to read the instructions as I go along I tend to take too long and the project fails. ---

Thanks for trying, but it didnt help. Maybe the remote has gone bad. I suppose I can buy one on the internet and try this again. I am sure I would still be ahead of taking it to the dealership.
